Check Digit Verification of cas no
The CAS Registry Mumber 111969-15-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,9,6 and 9 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 111969-15:
(8*1)+(7*1)+(6*1)+(5*9)+(4*6)+(3*9)+(2*1)+(1*5)=124
124 % 10 = 4
So 111969-15-4 is a valid CAS Registry Number.
